Application filed May 21,

To all whom t may concer/11,.

Be it known that I, I/VILLIAM WILLIS, a.

citizen of the United States, residing at Pawtucket, in the county ofProvidence and State of Rhode Island, have invented certain new andusefulv Improvements in Automobile- Signals, of which the following is aspecification.

My invention relates to signals for automobiles .and other vehicles.

The essential objects of my invention are facility of operation;portability and adjustability for attachment and use; inexpensiveness ofconstruction; and certainty and accuracy of spring action.

To the .above ends essentially my invention consists in such parts andin such combinations of parts as fall within the scope of the appendedclaims.

In the accompanying drawings which form apart of this s ecication,

Figure 1 is a ront elevation of my signal,

Fig. 2, a section of the same on line 2-2 of Fig. 1, Y Y

Fig. 3, a partial section ofthe same in extreme open Y position taken online 3-3 Fig. 4, 'a section on line 4--4 of Fig. l.

Like reference characters indicate like parts throughout the views.

In detail my device comprises .a vertical shaft 7 provided with alongitudinal channel or recess 8 extending from the top of the shaft toan intermediate portion thereof and forming a longitudinally disposedlateral opening 9. The channeled portion forms a housing or seat for .anindex arm open along one side and comprising front and rear walls 1l andone side wall 12. In the bottom of the recess is a transversely disposedpin or pivot member 14 passing through an opening 15 near the lower endof the index arm 16 whose upper end projects beyond the housing and inthis instance terminates in an arrow head point 17. The recess 8 issomewhat deeper at its closed side as at 19 and from this pointcontinuing upwardly some distance the wall 12 is cut away to form alongitudinally disposed slot 2O to permit passage therethrough of thelower end of theindex .arm when the latter is tilted. Extendingdownwardly in the lower-end of the shaft from the portion 19 of recess 8is a cylindrical hole 22 transversely of whose lower portionA extend ascrew or pin 23 to which is attached the lower Speccation of LettersPatent.

end'of a helical spring 25 in which upper end is a loop 26 through whichpasses one end of a link 27 whose other end passes through Ian eye orring 28 fast to the rear side of the shaft 7 near its lower end. Forhousing purposes a iat casing 30 is provided extending laterally fromthe shaft and fixed to the latter by attaching screws 34 passin throughan extension 35 on the lower en of the casing. The top of the casing isopen as well as the side adjacent the shaft 7 whereby a chamber 36 isformed to allow room for the tra-vel of the arm when the latter istilted. A bracket is provided having a base 38 fixed by an attachingscrew 39 to the side of the shaft and extending downwardly within thecasing to the upper portion of the opening 20 where it forms a stopagainst excessive depression of the arm 16. Extending horizontally fromthe bracket base is a rectangular body or frame 40 registering with thetop of the casing, transversely of which is a pintle 41 uponwhich ismounted a pulley or roller 42. At intervals in the side of the shaft 7are guide eyes 44, and near the top of the former is fast a pulley 47. Aflexible member 49 has its lower end attached to the eye 28 and passesover the roller or pulley 42, through the guide eyes 44, and over thepulley 47. Its end which depends from the pulley has attached thereto ahandle 50.

The device may be attached by screws therethrough or. otherwise to anypart of an automobile or other vehicle .at a point convenient for thedriver to grasp the handle 50. Normally the parts are in the positionshown in Figs. 1 to- 3 inclusive. By drawing the handle 50 the arm ismovable to any desired radial position within an arc of ninety degrees.In Fig.4 3 the arm 16 is shown horizontally or in position to indicatethat the driver isV going to turn to the right. An intermediate positionof the arm is a signal to the left. The construction, arrangement, andrelative location of the spring 25 permits free and effective action ofthe arm.

In a device of the character described, a shaft provided with alongitudinal recess extending from an intermediate portion to its topand one side, and with a vertical hole extending downwardly from therecess, an indicator arm pivotally mounted at a short distance from oneend in the lower portion of the shaft normally seatedin the recess, ahelical spring in the hole, a pin on the loWei portion of the holeengaged with the lower endY of the spring, an eye on the side of the.arm oarrying the other end of the spring, said shaft` 5 being providedwith a lateral slot to permit the passage of the spring, and alloy:rplay .for the inner end of said arm, a pulley on the shaft above theeye, guides on the Shaft 'and the guides.

YIn Ytestimony whereof I have alxed my signature.
